The KUPO ETI-P18 is an 18-leaf manual iris for Pacific / Freedom, giving these profile-style luminaires a controlled circular aperture for specials, isolation, and spill management. Its listed dimensions are specific to the Pacific / Freedom format rather than the S4 iris group.
Why It Matters
Pacific / Freedom need the correct accessory size if the iris is going to sit properly and operate smoothly. ETI-P18 gives that fixture family a dedicated 18-leaf option with the same heat-resistant leaf construction used across the ETI range.
